an amusing acronym disguised as a silly word. Dilligas stands for "do I look like I give a shit?" You can say it to your parents, your kid sister, your maiden aunt, really anyone who is annoying you, but whom you do not want to anger.

eddie: So anyway, as I was saying, to make a long story short, in other words, as God as my witness, between you, me, and the fencepost..................
freddie: hey man, dilligas?
eddie: what's that supposed to mean?
freddie: do i look like I give a shit?
eddie walks away angrily, muttering to himself.
freddie smiles, thanking his good fortune at discovering UD.
